Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
The specific embodiment
Be described further below in conjunction with the specific embodiment of accompanying drawing the utility model.
A kind of embodiment of follow-up bridge air bag air-charging and air-discharging system
As shown in Figure 1; This follow-up bridge air bag reverse gear system of charging and discharging comprises two identical gas unit that charge and discharge, and each charges and discharge the gas unit and all comprises air bag height-control valve 1, normal open electromagnetic valve 2, by pass valve 3, follow-up bridge air bag 4, jackshaft air bag 5 and height-control valve admission line 6.Height-control valve admission line 6 links to each other with 1 mouthful (admission port) of air bag height-control valve 1; 21 mouthfuls (air extractor duct) of air bag height-control valve 1 links to each other with 1 mouthful (normal open mouth) of normal open electromagnetic valve 2; 22 mouthfuls (air extractor duct) of air bag height-control valve 1 links to each other with the admission port of jackshaft air bag 5; 2 mouthfuls (normal open mouth) of normal open electromagnetic valve 2 links to each other with the admission port of follow-up bridge air bag 4, and 3 mouthfuls (nc port) of normal open electromagnetic valve 2 links to each other with 1 mouthful (admission port) of by pass valve 3,2 mouthfuls (air extractor duct) and the atmosphere of by pass valve 3; The electrical control mouth of normal open electromagnetic valve 2 is used for linking to each other with reverse gear signal circuit 7, and it is 0.2MPa that the response pressure of by pass valve 3 is got definite value.
